[Completed] [Q] LG L9 BootLoop ms769 HELP??????

i have tried so many threads, and most using adb or fastboot, but my device is never found, it always says waiting for OMAP44xx device, even though its connected one way or another, it has a bootloop on the lg logo. I have root, i have a LOCKED bootloader ,with busybox and cwm recovery. I tried installing xposed Installer, but to my dismay i put recovery automatic or something like that and now there is a boot loop. Please Help Me, they say this is an unbricable phone, but i am highly doubting it now.

[Completed] LG G3 D850 for AT&T Bootloop, No Fastboot, Crash Kernal, LG Flashtool Stuck at 6%

Hello I have an AT&T LG G3 D850 and for some reason when I attempt to go this I get stuck at 6% and it will get stuck at "LAP Bin_User_Mode" and finally would say "Erase Command Failed". To my knowledge the partition on the phone has been wiped from TWRP making the phone at this point absolute useless. The only mode I can access is Dowload Mode and TWRP Recovery but even in recovery I cant do anything because the partition has been wiped. What can I do at this point? Thanks
